Abstract

This paper presents the development of an ultrasonic rat repellent device that integrates a Passive Infrared (PIR) sensor with an Arduino Uno microcontroller. The PIR sensor detects rat presence within a 5-meter range, transmitting this information to the Arduino Uno. In response, Arduino activates a buzzer to emit ultrasonic waves at frequencies specifically chosen to repel rats. The device also includes an LED as a visual indicator and an LCD for a real-time status display. The design incorporates jumper cables and a breadboard for assembling the circuit, with additional components, such as a potentiometer and battery connectors, for efficient operation. The effectiveness of the device depends on the precise programming of the Arduino, which controls the activation and intensity of ultrasonic emission. This innovative approach offers a noninvasive, environmentally friendly alternative for managing rat infestations in various settings.

Abstract

The grounding system is very important in a building electrical installation. The socket is an electrical installation component that functions as a power supply line to electronic equipment which in the PUIL 2000 rules must be connected to the building grounding system. As the installation age of a building increases, the grounding system will degrade. In this research, a grounding detector has been made at the socket to determine whether the socket is connected to the grounding system. In this tool there is a plug-shaped component that is mounted on a socket. From the test results, the tool can detect the voltage, leakage current and ground connectivity detection which is displayed on the LCD screen. The optocoupler sensor installed around the wheel can read the wheel rotation well so that the distance measurement data between the outlets has a good accuracy rate approaching 100%, namely 99.26%. The Arduino Mega 2560 Pro microcontroller manages the overall measurement data results and transfers the data to the memory card. The duration of use of this tool can be up to 10 hours, which is quite a long time to be used for the purpose of checking the grounding condition of a building with this tool.

Abstract

The increasing use of electrical energy is inversely proportional to the diminishing fossil energy sources. New and Renewable Energy  is one of the alternative energy that is being developed now. One of the energy used in the utilization of new and renewable energy is wind energy. In this study, we will discuss the manufacture of blades made from Expanded Polystyrene (EPS) Foam which is intended for wind turbines at low wind speeds. The use of this material is used and is able to form a blade with a weight of ± 300gram. This blade uses an Inverse Tapper type blade, which is a blade with an enlarged geometry at the tip, this geometry has a large surface so that it can receive more wind so that it can rotate at low wind speeds. The design and manufacture of blades is carried out using Aeolus ASP software which is open source on several analysis features and serves to determine the performance of the blades as well as to analyze aerodynamics and optimization of the shape of the blades designed to use Blade Element Momentum (BEM). This blade is capable of producing a voltage of 12.09 V. In the process of making the blade using wire cut to create geometry with National Advisory Committee for National Aeronautics (NACA) 4412 airfoil. The blade uses layers of balsa wood and monocote plastic sheets, and uses wood plywood as the base of the blade.

Abstract

Upaya efisiensi energi dapat diwujudkan melalui penerapan smart energy meter pada rumah tangga yang akurat dan terkalibrasi. Salah satu tantangannya ada pada keterbatasan akurasi sensor tegangan, salah satunya ZMPT101B yang banyak digunakan namun belum banyak dikaji secara khusus dalam literatur ilmiah. Penelitian ini mengisi kesenjangan studi kalibrasi sensor tegangan ZMPT101B dengan pendekatan matematis yang sistematis dan evaluasi komprehensif menggunakan data rentang penuh 5–250 V. Tujuannya adalah meningkatkan akurasi pengukuran tegangan listrik, khususnya untuk aplikasi meteran energi rumah tangga. Sensor ZMPT101B dihubungkan dengan mikrokontroler Arduino Uno, dikalibrasi, dan diuji pada rentang tegangan 5–250 V dengan interval 5 V. Proses kalibrasi dilakukan dengan dua model matematis dari metode least-square, yaitu regresi linear dan regresi polinomial orde dua. Hasil metrik evaluasi menunjukkan bahwa model regresi linear dan model regresi polinomial mampu menurunkan deviasi pengukuran hingga 2 V (RMSE) dengan kesalahan relatif 2% (MAPE). Temuan tersebut menyoroti potensi metode kalibrasi sistematis untuk mendukung keandalan meteran energi pintar berbasis IoT berbiaya rendah, sehingga mendukung efisiensi energi rumah tangga di era digital

Abstract

Pentanahan merupakan hal penting untuk melindungi sistem tenaga listrik. ITERA sebagai kampus baru dan pada tahap pengembangan membutuhkan pengujian sistem pentanahan untuk rencana pembangunan fasilitas dan fasilitas pendukung kegiatan kampus. Semua bangunan harus memiliki keandalan pentanahan sehingga gangguan pada peralatan listrik dan elektronik tidak membahayakan keselamatan. Faktor tanah menjadi salah satu parameter penting karena memiliki karakteristik nilai resistansi berbeda yang tergantung pada jenis tanah, jenis sistem pentanahan, suhu, kelembaban, kandungan elektrolit dalam tanah dan lainnya. Untuk alasan ini, perlu untuk membangun sebuah sistem yang cocok dengan karakteristik tanah ITERA sehingga nilai resistansi tanah yang kecil tercapai dan mencapai titik aman, maksimum 5 ohm (PUIL 2000). Uji pentanahan dilakukan dengan menggunakan metode variasi kedalaman dari dua jenis elektroda dan variasi konsentrasi dua jenis zat tambahan. Pada penelitian ini digunakan garam dan bentonite sebagai zat campur tanah. Pada kondisi awal dengan variasi kedalaman 20 cm hingga 100 cm pada dua jenis elektroda tanpa penambahan zat tambahan diketahui bahwa resistansi bumi di atas 5 ohm yang tidak mencapai kondisi aman. Penambahan bentonit dan garam menyebabkan resistensi tanah berkurang dengan meningkatnya konsentrasi zat aditif dan meningkatnya kedalaman implantasi elektroda. Nilai resistansi tanah yang aman dapat diperoleh dengan menggunakan elektroda mesh pada konsentrasi 7 kg garam dengan kedalaman 30 cm dan 40 cm pada konsentrasi 7 kg bentonit, sedangkan menggunakan elektroda batang, nilai aman dapat diperoleh dengan menambahkan 7 kg garam atau 7 kg bentonit pada kedalaman 80 cm.

Abstract

The increasing demand for energy and the need for environmental sustainability have led to the adoption of renewable energy sources, such as micro-hydropower plants (PLTMH), in isolated communities in Indonesia. However, voltage and frequency instability issues are commonly encountered in PLTMH systems, which undermine their performance. In 2009, a micro-hydropower plant with a capacity of 30 KW was built in Renah Kemumu village.  Ranah Kemumu village is located in Jangkat sub-district, Merangin district, Jambi province. In this study, the voltage and frequency instability of PLTMH in Renah Kemumu Village were investigated. The methodology employed in this study was observational. The voltage and frequency data were measured and recorded during peak load hours from 18.00 to 21.00 over one month. The percentage increase relative to the standard voltage and frequency was calculated. Boxplots were generated to visualize the distributions. The voltage measurements showed maximum and minimum values of 270 V and 264 V, representing increases of 22.72 % and 20.45% from the 220 V (standard set by the power utility (PLN)). The frequency ranged from 66.32 Hz to 57.46 Hz, corresponding to 30.92% and 14.92% deviations from the 50 Hz (standard set by the power utility (PLN)).  These values exceeded the tolerance limits of the State Electricity Company of Indonesia. The analysis indicates that the voltage and frequency levels at the PLTMH in Renah Kemumu Village are unstable during peak loads, with fluctuations stemming from changing water flows, load currents, and weather conditions
